Syphilis is a sexually transmitted infection caused by the bacterium Treponema pallidum subspecies pallidum. The signs and symptoms of syphilis vary depending in which of the four stages it presents (primary, secondary, latent, and tertiary). The primary stage classically presents with a single chancre (a firm, painless, non-itchy skin ulceration) but there may be multiple sores.
After a person gets syphilis, the disease begins in the primary stage. A person gets syphilis by having sex with a person who has syphilis. Usually, the person who has syphilis has wounds on their genitals caused by syphilis. Touching these wounds during sex (including oral sex or anal sex) can give a person syphilis.
